Abstract:
The present invention provides a compound capable of forming an irregular wrinkled structure, a composition containing the compound, a film having the irregular wrinkled structure, a method of forming the film, and an organic light emitting diode comprising the film. The film can be formed with the irregular wrinkled structure by simply coating the compound of the present invention, and curing using UV rays or heat. By applying the formed film to the organic light emitting diode, light emitted from the organic light emitting diode is scattered on the surface of irregular wrinkles and is extracted to the outside after controlling the optical wave or total reflection. A random structure located on the outside of the diode functions as a light extraction unit for improving the light efficiency of the organic light emitting diode.
Abstract:
PURPOSE: A display device is provided to improve readability and color reproducibility and to save power consumption using a light emitting part for self emission and a pixel part for reflective emission. CONSTITUTION: A light emitting part(230) emits first wavelength light. The light emitting part includes a first electrode(231), an organic light emitting layer(233), and a second electrode(235). A pixel part(270) emits second wavelength light using reflected light. A capping layer(250) is laminated between the light emitting part and the pixel part. An optical sensor(260) measures the intensity of outside light. A control unit(280) operates the light emitting part and the pixel part according to the intensity of the light measured by the optical sensor.
